Title: Improvements in drawer locking and release mechanism for coin freed vending machines
IPC: G07F11/18
Filed: 1936-11-04
Abstract: 465,255. Coin - freed article delivery apparatus. HARPER, P. S. Nov. 4, 1936, No. 30021. [Class 27] Coin action, with stationary coin forming abutment ; coin-discharging mechanism.-The delivery drawer of a coin-freed vending machine is normally locked against outward movement by engagement of the end of a locking member, pivoted thereon, in a stationary catch slot, the flat face of an inserted coin masking the catch slot to prevent such locking engagement and permit opening of the drawer. As shown, the drawer 1 slides on a base-plate 4 having downturned parts 5 and 6 by which the whole mechanism is secured as a unit to the machine. A coin inserted through a slot in the drawer enters a passage between the part 5 and a yoke 13, and is retained in a position to cover a catch slot 11 in the part 5 by the sides of a recess in a lever 12 pivoted at 12a to the yoke. A pin 18, depending from the drawer and working in slot 19 in the base plate 4, carries a locking lever 17 biassed by a spring 20 to hold a pin 24 against an arm 23 on the coin lever 12 which is thereby held in coin-supporting position. As the drawer is pulled out, the end 25 of the locking lever travels over the rear face of the coin ; the pin 24 engaging a second arm 26 on the coin lever to displace it and release the coin at the completion of the outward movement. In the absence of a coin before the slot 11, the end 25 of the lever 17 locks in the slot and prevents all but slight movement of the drawer. A spring 31 bears against a roller 29 carried by the drawer, and is shaped so as to exert a substantial return force only during the initial movement before the locking lever 17 has cleared the slot 11 : it completes the final portion of the return movement of the drawer with a snap action. Fraud, preventing.-A double-acting pawl engages a rack at the side of a recess underneath the drawer to ensure a full movement in either direction.

Abstract: 484,994. Copying - telegraphy. FINCH, W. G. H. Nov. 9, 1936, No. 30581. Convention date, Nov. 11, 1935. [Class 40 (iii)] Signals of varying amplitude are changed into signals of constant amplitude but varying frequency, or produce marks of constant blackness at varying intervals. Transmitter. Picture signals amplified at 6, Fig. 1, are applied to a solenoid 8 to control the position of a plunger 9 which carries the contact 15 of an interrupter 16. The frequency of vibration of the armature 17 is stated to depend on the position of the contact 15, so that constant amplitude, varying frequency signals are produced in transformer 31. In a modification, the plunger 44, Fig. 2, controls the condenser 55 of an oscillator 57 which beats with a constant frequency oscillator 57<1> to give the desired signals at 62. The rotary condenser 55 may be replaced by a " squash " condenser varied by a plunger operated by a moving coil, Fig. 2a (not shown). Receiver. The constant amplitude signals may be applied to moving coil carrying the recording stylus, Fig. 3 (not shown). Where the received signals are of varying amplitude, they may be applied to a solenoid 102, Fig. 5, to control a plunger 104 which carries the contact 110 of an interrupter 115, the armature 112 actuating the stylus 122. In a modification, the armature is positioned at one side of the electromagnets, Figs. 6, 7 (not shown). The contact 110 may be carried by a lever actuated by the plunger 104, Fig. 8 (not shown). In a further modification, the received amplitude modulated signals are applied to a moving coil 150, Fig. 9, whose former also carries a coil 152 energized with alternating current from a source 154, so that the stylus 82 produces marks at varying intervals. In a similar way, the stylus may be actuated by an armature driven by a coil assembly comprising three coils, energized by the received signal, alternating current and direct current respectively, Fig. 10 (not shown). U.S.A. Specification 1,985,654 is referred to.

Title: Apparatus for the supervision and control of the stoppages and diminutions of speed of railway trains, tramways and the like
IPC: B60T7/12
Filed: 1924-12-19
Abstract: 243,547. Rodolausse, E. Dec. 19, 1924. Addition to 162,617. Track apparatus for stopping trains.-To the apparatus according to the parent Specification, there is added a means, Fig. 1, for bringing about an earlier application of the brakes if the brakepipe pressure is below the normal, the said means being a modified form of a part of the apparatus described in Specification 206,040, and a means, Fig. 3, for maintaining the brake application until the train is stopped. A cylinder 10 is in communication with the brake pipe and the piston 11 assumes a position corresponding to the pressure existing at any time and determines the position of a lever 15 carrying a roller 17, which bears against a lever 18 pivoted to the lever 8, which is controlled by the cam 7 as in the parent Specification. The lever 18 bears against a roller 19 on the supervising index lever 6, and the combined action is such as to set this lever 6 to a lower speed indication for any position of the lever 8 as the brake-pipe pressure is reduced. The brake application is maintained by latching in its depressed position the rod 4a by means of a latch 21 which is put in operation by a cylinder 26 supplied with exhaust air from the brake-valve 37 through a normally closed valve 28 which is opened towards the end of the revolution of the cam 7. Alternatively, the latch 21 may be moved mechanically by the cam 7. The latch 21 engages above the abutment 23 on the rod 4a and prevents the latter from rising until the latch 21 is reset either by engagement of the speed-indicating pointer 1 with the latch 34 or by manual release of the latch 34 by the cylinder 35.

Checking watchmen &c.-A key or control device for operating a watchman's clock is incorporated with mechanism to be supervised and is so controlled that, unless the part of the mechanism to be checked is in other than a normal desired position, the recording clock cannot be operated. The device as shown in Figs. 1, 2 and 3, adapted for use with a valve comprises a T-shaped bracket or frame with oppositely extending flanges 16, 17 and a hollow stem 21, the flanges being slotted for receiving bolts adapted to secure the bracket to the members 11, 12 of the yoke supporting the valve stem and the hollow stem being provided with a key or control device 24 held therein by a bolt 25 extending through opposite walls of the stem. The bolt 25 passes through a slot in a longitudinally movable bar 23 extending through a hole in the base of the bracket and co-operating with the screw-threaded stem 15 of the valve. The shank 27 of the watchman's clock is adapted to fit over the extending portion of the key the extent of the insertion of the key depending on the position of the bar 23. When the valve is fully open the bar is in alignment with a slot 26 in the stem 15 and the key can be inserted to its full extent in the shank 27 to render the recording mechanism of the clock operative. In any other position of the valve stem the bar engages the threads of the stem and thus prevents full insertion of the key and renders the recording-mechanism inoperative. The key is protected by a cover 28.
